Zolo didn't show supreme CoA vs Pica.
Thats a very dumb ZKK level argument.
Zolo amplified his CoA sword attack with a Sanzen Sekai sword technique, so the only thing we know happened was the SKILL difference. That page only shows Pica didn't have much better CoA than Zolo so Pica couldn't overpower both Zolo's sword technique + his special swords + his CoA.
If Zolo wanted to show a better CoA, he wouldn't use any sword skill technique vs Pica to challenge Pica's CoA, he would beat him with a barehanded CoA hit, just like Pica dropped using his sword, Zolo should do the same, or at least a random sword swing without using any sword technique would be better, but even the latter wouldn't be enough since
special swords such as Wado, Enma or Kitetsu all have very high quality steel material, its still a big advantage without even a sword skill technique.
Sanji is currently have better attack power than before because he now has exoskeleton + CoA combination toughness, while Zolo was using special high quality sword + CoA combination since the Time Skip.
To show how big of a difference special swords are, look how Wado Ichimonji wasn't broken vs. Mihawk's attack while his
other 2 swords got broken,
And look how Big Mom specifically
mentioned about special sword Enma, not about Zolo's Haki:
Zolo used: 3 special swords + 3 swords style sword skill Sanzen Sekai + CoA VS. Pica's Barehanded CoA. Of course Zolo was going to cut Pica unless Pica had much much greater CoA Haki than Zolo's.
Luffy overpowered a superior CoA user Katakuri by using G4 technique, by using sword skill or DF they can even overpower a superior CoA, let alone close level CoA.
PreTS Luffy without even Haki,
overpowered Haki user Marigold's Haki Barrier via G2 DF technique.
Even Hakiless Sword Skill or Hakiless DF ability can even overpower Haki barriers sometimes.
Zolo wasn't even winning vs. Fodder Nyaban Brothers without using his 3 Swords Style:
Zolo: ''You don't know the difference between, 'using three swords' , and using 'three swords style'!''
--- Chapter 0033
Zolo: ''I'm not used to fighting with only one katana, but I have no choice...''
--- Chapter 0032
Zolo only won vs. Fodder via SWORD SKILL difference.
Only way to know if Zolo's CoA is better or not:
1- Zolo is not going to amplify his attack with a Sword Skill: Sanzen Sekai technique, instead Zolo is going to swing his sword randomly
without any sword skill technique, and without using any special high quality steel sword, and cut Pica's CoA.
2- Zolo won't use special steal swords vs barehanded CoA users, or Zolo with barehands only will block a CoA imbued attack from Pica without taking any damage.
Zolo admitted if Pica's Haki was stronger, even with his special steel swords + sword skill + CoA wouldn't work. But Pica's CoA wasn't much stronger. That only confirmed Pica's CoA wasn't stronger, not that Zolo's CoA was stronger than Pica's.
Example: Katakuri and Luffy clashed with barehands,
Katakuri overpowered Luffy via superior CoA.
- Then Luffy with inferior CoA Haki, used DF technique G4 + CoA and overpowered Katakuri's CoA. DF powers + techniques or special high quality swords + sword skills makes a huge difference during CoA clashes.
- Vergo and Sanji clashed their legs, Vergo damaged Sanji's leg via superior CoA.
- Vergo and Smoker clashed the weapons, Vergo used bamboo, Smoker used jitte, Vergo's bamboo overpowered Smoker's jitte via superior CoA.
To prove Zolo has better CoA than Pica's CoA, Zolo needs to fight with the first 2 conditions that I mentioned above.
